Errors that can occur during module resolution

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotFound

Module file not found

Fields

path: Vec<String>

Logical module path that failed to resolve.

searched: Vec<PathBuf>

Filesystem locations that were searched.

CircularImport

Circular import detected

Fields

cycle: Vec<Vec<String>>

Ordered import cycle that was discovered.

ImportConflict

Name conflict between imports

Fields

name: String

Imported symbol name that collided.

module1: Vec<String>

First module providing the name.

module2: Vec<String>

Second module providing the same name.

PrivatePredicate

Attempted to import private predicate

Fields

name: String

Predicate name that is not exported.

module: Vec<String>

Module that owns the private predicate.

PredicateNotFound

Predicate not found in module

Fields

name: String

Predicate name that could not be found.

module: Vec<String>

Module that was expected to export the predicate.

ParseError

Parse error in module

Fields

path: PathBuf

Source file path that failed to parse.

message: String

Human-readable parse failure message.

Trait Implementations

impl Clone for ModuleError

fn clone(&self) -> ModuleError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ModuleError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ModuleError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ModuleError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ModuleError> for XlogError

fn from(e: ModuleError) -> Self

Converts to this type from the input type.
